example.c - C code that causes a segfault
$ gcc --version
gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0
Copyright [...]
$ gcc example.c
gcc: internal compiler error: Segmentation fault (program cc1)
Please submit [...]
$ cat example.c
#include<stdio.h>
int main(void) {
int x = !!![one megabyte of exclamation marks]!!!1;
printf("%d", x);
return 0;
}

The same error occurs for the corresponding g++ command.
